実験手順

1,8-Diazabicyclo[5,4,0]undec-7-ene (0.93 g, 6 mmol) was added dropwise to a stirred suspension of 3-(acetylamino-methyl)-phthalic acid dimethyl ester (1.61 g, 6.0 mmol) and aminoglutarimide hydrochloride (1.0 g, 6.0 mmol) in DMF (15 ml). The mixture was then heated to 120° C. for 24 hours. The cooled mixture was concentrated in vacuo and the residue was stirred with water (25 ml) and dichloromethane (20 ml). The resulting slurry was filtered to give 0.45 g (22%) of the product as a gray solid. Recrystallization from methanol gave a white solid: mp 177–179° C.; 1H NMR (DMSO-d6) δ (11.02 (s, 1H), 8.36 (t, J=5.8 Hz, 1H), 7.74–7.55 (m, 3H), 5.05–4.98 (dd, J=5.3 and 12.5 Hz, 1H), 4.57 9D, j=5.9 Hz, 2H), 2.84–2.70 (m, 1H), 2.51–2.34 (m, 2H), 1.95–1.91 (m, 1H), 1.79 (s, 3H); 13C NMR (DMSO-d6) δ (172.85, 169.89, 169.81, 167.56, 167.05, 139.37, 134.83, 133.35, 131.58, 127.14, 121.94, 48.91, 37.84, 30.98, 22.54, 22.05; Anal. Calcd. For C16H15N3O5+0.96 water: C, 55.45; H, 4.92; N, 12.12. Found: C, 55.27; H, 4.82; N, 12.00.
